I've bought the SS guards for the rad and the oil cooler, and couldn't get the screw out of the side of the rad and the screw from the oil cooler. does my head in
My radiator ones came out fine but I did replace them all with stainless bolts when I put the new cover on, the radiator screw for the guard is a lost hope I think until I have a reason to drop the headers and I can get proper access to it to rip it out.
